[Wine] Some (Steam) applications not launching

[Tetsuro]

It seems to happen only with Steam games. Sometimes they fail to 'start'. If I go to Gnome System Monitor it says like: 'name of the process / Sleeping / 63.6 MB / futex_wait_queue_me'. 
It happens with a lot of games, sometimes they start and sometimes they got stuck (the same that was launching before at a later time isn't launching anymore).

Any suggestions?
